摘要

根据已知的表征，一个函数\(f\)属于包含在\(L^p(\mathbb{R}^n)\)中的函数及其广义一阶导数的Sobolev空间\(W^{p,1}(\mathbb{R}^n)\)，精确地当存在一个函数\(g\in L^p(\mathbb{R}^n)\)使得

Pointwise Conditions for Membership of Functions in Weighted Sobolev Classes

According to a known characterization, a function \(f\) belongs to the Sobolev space \(W^{p,1}(\mathbb{R}^n)\) of functions contained in \(L^p(\mathbb{R}^n)\) along with their generalized first-order derivatives precisely when there is a function \(g\in L^p(\mathbb{R}^n)\) such that
